Fix several tests failing due to missing CMAKE_OBJDUMP in CMake test fixture

In llvm#37, test_suite.py started requiring the CMAKE_OBJDUMP variable
from the set of CMake variables. Various tests were using a fake CMake
test fixture which defines various CMake variables, however CMAKE_OBJDUMP
wasn't added in llvm#47, breaking a bunch of tests.

This was probably never noticed because the tests were completely
broken back then, I assume they were not being run on a regular basis.
